TOOL FOR FORMING GROOVES lN BOTTLE-MOUTHS.

EPECIPICATION forming part of Letters Patent No. 369,890, datedSeptember 13, 1887.

Application filed August 4, 1887. Serial No. 246,130. (No model.)Patented in England July 9, 1885, No. 8,299.

To all whom, it may concern:

Be it known that I, BENJAMIN STONER, a subject of the Queen of GreatBritain, residing at Stairfoot, near Barnsley, in the county of York,England, have invented new and useful Improvements in Tools for FormingGrooves in Bottle--Mouths, (for which I, in conjunction with DanRylands, have obtained a patent in Great Britain, No. 8,299, bearingdate July 9, 1885,) of which the following isa specification.

My invention relates to improvements in tools for forminggroovesinbottle-mouths; and the objects of my improvements are, first, to formthat portion of the mouths of bottles which comes below the grooves of auniform size, so that the internal stoppers of such bottles are neverable to stick in the necks, and, second, to dispense with the ordinarypresser and springs, so that the tool may be more simple inconstruction. I attain these objects by the mechanism illustrated in theaccompanying drawings, inwhich- Figure l is a plan of improved tool.Fig. 2 is a front elevation, and Fig. 8 is a plan, with a portion ofhandles and standard removed and a bottle-mouth shown in section onplug. Fig. 4 is a plan of modified form of improved tool having aportionof the standard and bandles removed and a section of a bottle-mouthshown on'plug. Fig. 5 is an enlarged partsectional plan of plug with itsmovable part closed. Fig. 6 is a plan of same with its movable partopen. Fig. 7 is an enlargedplau of modified form of plug having themovable portions apart, and Fig. 8 is a part-sectional plan of the samewith the movable portions closed. 7

Similar letters indicate corresponding parts.

Referring to Figs. 1, 2, 3, 5, and 6, the plug or mandrel A is made intwo parts, 0 and d. The part (I consists of a swiller, d, and a portion,d". This portion 01" forms the interior of bottle-mouth above thegroove. The part c is movable and works on a spindle, g, which has abearing in the hole 6. The edge e of the part 0 forms the interior ofthe bottle-mouth below the groove, and the cutter f, which may be eithermade with orattached to the part 0, forms the groove in thebottle-mouth. The spindle g, which is preferably made in one piece withthe part c, is placed eccentric to or a little out of center of saidpart. It passes through the hole 6 and has a bearing in the crossbar l.

A crank, 10, is secured to the spindle g by 5 means of a set-screw, as,and is connected to the handle or of tongs B by means of the rod y. Thepart (Z of the plug a is attached to the bridge J by means of theset-screws r r. The

standard 8 and nuts t t i connect the bridge J to the tongs B. The diesat u are secured to the handles m m by means of the nuts '0 22.

Referring to Figs. 4, 7, and 8, the plug A has two movable parts, 0 c,which have spindlesg 9. These pass through the holes 6 6, formed 6 S.When the handles m m are apart, as shown at Fig. 1, the movable part cof Figs. 1, 2, 3, 5, and 6, or parts 0 0, Figs. 4, 7, and 8, of plugAare closed, as shown at Figs. 1, 2, 5, and 8, in which position they,togetherwith the portion d are pressed into the'mouth of the bottle required to be formed. Then the handles m m are pressed to until theyobtain the position shown at Figs. 3 and 4. This pressing to of thehandles m m causes the rods'yg to turn the cranks w w, which, beingsecured to the spindies 9 9, turn said spindles also, and the spindle orspindles g 9 being either attached to or made with the portion orportions 0 c, the said portion or portions 0 c necessarily turn also,

thus bringing the cutter or cutters ff and edge 0 or edges 0 c to theposition shown. at Figs. 3, 4, 6, and 7. The tongs are held in thisposition during the time the bottle is being formed in the ordinarymanner.

After a satisfactory month has been formed, 5

the handles m m are released, when the rod or rods yg draws or draw backthe crank or cranks w 'w, and so brings or bring the'niovable portion orportions 0 c to positions shown at Figs.

1, 2, 5, and 8, in which position the plug A The rods 3/ 3 connect thecranks 7o 2 r 369,890 a it may be withdrawn from the mouth of thebotsimilar plug, the crank w or cranks w w, contle without interferingwith the groove in innected to and operating with the tools, subteriorof the bottle-mouth.
